From Vulgar Latin *advērāre, from Latin ad + vērus (true). Compare Italian avverare, Romanian adeveri, Spanish adverar.




  1. (transitive) to uncover, to reveal
  2. (takes a reflexive pronoun) to prove (to be); to transpire
    Il s'est avéré plus compliqué qu'on avait imaginé.
    It proved more complicated than we'd imagined.
    Il s'avère qu'il s'est suicidé.
    It turns out he committed suicide.


This verb is conjugated like céder. It is a regular -er verb, except that its last stem vowel alternates between /e/ (written ‘é’) and /ɛ/ (written ‘è’), with the latter being used before mute ‘e’. One special case is the future stem, used in the future and the conditional. Before 1990, the future stem of such verbs was written avérer-, reflecting the historic pronunciation /e/. In 1990, the French Academy recommended that it be written avèrer-, reflecting the now common pronunciation /ɛ/, thereby making this distinction consistent throughout the conjugation (and also matching in this regard the conjugations of verbs like lever and jeter). Both spellings are in use today, and both are therefore given here.
